I'll take the opposite tack on the Remlin parts, I'd just as soon have one made up with those.
When Remington first took over Marlin there were widespread reports of a drop in quality since the folks at Remington didn't have the human knowledge to use the machinery properly. But they invested in new machinery and from what I read the later Remington Marlins were as good if not better than what Marlin put out.
Meanwhile, my experiences with recent Ruger products has been abysmal to say the least. Now, that's confined to one specific product line but I can see the cheapening of various things across a few of their handgun lines. Have only bought a couple of new Ruger rifles in the last few years but even those don't hold a candle to the solid feel of the ones made 10, 15 or more years ago. (Not counting the batch of LH SS .223 Hawkeye's several years ago of which about half had bent barrels
)
